select by opacity

hi all,

here is a simple idea, which would be very useful in certain situations... on the 'select by colour' or 'select by contiguous region' tool, it would be GREAT if there was a further option to select on the basis of opacity, from 0 - 100, within a given region....

thanks very much

josh

Hi,

I know it's not that simple as an extra option in these both tools dialogs, but does the following help you?:

1. In the Layers dialog right-click on that particular layer, select 'Alpha to Selection'.
2. Press Q to show the quick mask.
3. Use the Threshold Tool and play with the black and white triangle sliders to set the range -> this affects the selection. 4. Press Q again to hide the quick mask.

Kind regards,

Sven

Isn't that exactly what "Layer/Transparency/Alpha to selection" is all about?
